JSON to XML Converter — Clean, Escaped, Round-Trips With XML to JSON

Real-world use cases

• Build a SOAP request body from a JSON test fixture

  Your service talks REST/JSON internally but one legacy partner only accepts SOAP. Keep your test data as readable JSON, then convert it here right before the call. Steps: write the payload as JSON with the envelope's children as nested keys, use `@` keys for any `xmlns`/`soap:` attributes you need on the elements, set the root element to your operation name, leave the XML declaration on, copy the output into the `<soap:Body>`. Because attributes and text both escape correctly, an order note containing `Q&A` or a `<tag>` won't blow up the envelope.

• Generate an RSS 2.0 / Atom feed from a JSON content list

  You have a JSON array of posts from your CMS and need a valid feed for podcast apps or feed readers. Wrap the array under a key like `{ "channel": { "item": [...] } }` so each post repeats as `<item>`, map title/link/pubDate to child keys, and convert. The repeated-element behavior is exactly the RSS idiom, and escaping keeps post titles with ampersands ("Tips & Tricks") from breaking the XML. Paste the result into your feed file and validate.

• Author Android string/layout resources from JSON

  Android resource files (`strings.xml`, drawables, layouts) are XML, but it's often easier to keep source-of-truth content in JSON and generate the XML. Model `@name` as the attribute and `#text` as the value: `{ "string": { "@name": "app_title", "#text": "Toolora" } }` → `<string name="app_title">Toolora</string>`. Set 4-space indent to match Android Studio formatting and the declaration on for a proper file header.

• Convert a JSON config to an XML config for a legacy app

  Plenty of enterprise software (Spring beans, old .NET app.config, Tomcat server.xml) still reads XML configuration. Keep your config in JSON for diffability, then convert when deploying. Use nested objects for sections and `@` keys for attributes like `name`/`value`. The single-root rule means you set one wrapping element (e.g. `beans` or `configuration`) and the tool guarantees the output parses.

• Round-trip XML through JSON for bulk editing

  You received a large XML document, want to edit it programmatically (search/replace, reorder, filter), and your tooling is JSON-native. Run it through XML to JSON, manipulate the object, then bring it back here with the same `@attr`/`#text` settings to rebuild equivalent XML. Keep the attribute prefix and text-node key identical in both directions so element structure, attributes, and text survive the trip intact.

Common pitfalls

• Expecting multiple top-level keys to stay un-wrapped. XML allows exactly one root, so `{ "a": 1, "b": 2 }` is wrapped in `<root>…</root>`. If you want a specific wrapper name, set the Root element field — don't assume the first key wins.

• Pointing an `@attribute` key at an object or array. XML attributes only hold flat scalar text, so `{ "@meta": { "x": 1 } }` is silently skipped rather than emitting invalid `attr="[object Object]"`. Promote nested data to a child element instead of an attribute.

• Forgetting that element names get sanitized. A JSON key with spaces, colons, or a leading digit (`"order id"`, `"123"`, `"soap:Body"`) is rewritten to a legal XML name (`order_id`, `_123`, `soap_Body`). If you need the exact `soap:` namespace prefix preserved, that's a known limitation — declare the namespace and use a single-segment local name.
